I am using the default cover art playback and I am now hearing this as well.   Seems like the last day or so.  Not sure what build this was introduced though.  It only happens for me when a song is stopped completely and I then either play it again of select a new song. 

I am not hearing it in between track transitions.

It sounds more like a 'pop' too.

[JimH]

Any third-party plug-ins?  RhinoBanga's PlayingNow, for example?

[datdude]

Nothing other than standard cover art for playback, and no third party plugins either.

The noise is very subtle.  I tried using foobar and the pop goes away.

I turned off all dsp as well.  Is there any way to go to default playback settings as well, just to test?

I am also playing standard mp3 vbr's mostly ripped in MC.

Just to reiterate, the sound only occurs when no song is playing. And then a new song is started.

Even if that songs is paused and then I switch to another track, the pop DOES NOT occur.

Try switching playback between Direct Sound and WAV out.

Try updating the sound card drivers.

[datdude]

Yep, thats it, direct sound is the problem.  Wav out,  No issue.  I am using a laptop and I don't see any updated drivers listed.

Is there a problem with using wave out if this a local issue?

[hit_ny]

Try looking at CPU usuage, in XP i found direct sound gives the lowest overhead.

I don't see any reason to use wave out in XP.

It's about 2% more, oh well. 

Sounds the same though execept for the pop.

It's my guess that some sound card drivers work correctly with one and not the other.

[datdude]

Weird though, becuase I know for sure I did not have this problem very long ago with the same setup.

I guess I will have to look back into the earlier builds to see if it is still there.

JimH: I _still_ believe this is a bug in MC. How many other reports are needed to accept the fact? All this reminds me of "Comical Ali" ("There are no American infidels in Bagdad. Never!")

IMHO, one properly made report would help a lot. You would need to provide JRiver a way to reproduce the bug.

I can't reproduce it on my three different PCs (using the ASIO, Direct Sound, Wave Out or Disk Writer output modes.):
- a homemade desktop: MSI MB / P4 / Intel Chipset / XP home / integrated C-Media CMI9739A audio and Terratec DMX 6fire 24/96 soundcard
- a Fujitsu Siemens D-8820 laptop: P4 / SiS chipset / XP Home / integrated Realtek ALC202 AC97 audio
- a homemade desktop: Abit MB / AMD Athlon / VIA chipset / Win 2000 Pro / SoundBlaster 128 PCI soundcard

A proper report should include at least the following:
- complete system information (soundcard, chipsets, drivers etc).
- complete information about the used MC options.
- information about the last MC version that does not have the problem.
- a sample audio file (if the problem is dependent on the file format or size)

[datdude]

I think it is something specific on my computer now, as I have gone back pretty far in MC builds, and the pop is still there.

I have tried other programs like foobar and winamp, and there is no issue, so it is MC specific, but I must have changed something, somewhere, somehow.  I have messed with just about every playback option with no luck.

So, wave out it is!

AlexB, maybe i should talk to JRiver about employment possibilities as a professional beta tester  . What you are describing would take ages. I don't know what your occupation is, but i also have a life besides MC. Will try to provide more details, though.

Well, it's a bit hard to find a problem if all you have to go on is "its broken and it didn't used to be".

For something like that, all the info requested is needed to try to pin down what could be the problem. Lots of drivers, hardware, settings in MC, file formats, versions of encoders, phase of moon, etc.

I listed most of that.  And I know it didn't happen before.

Not a big deal though as wave out, seems to work just fine.

The default output method changed to DirectSound in MC 11.1.  The default buffering amount was also decreased.  Slow machines or ISA soundcards may not like this.

If you see sporadic clicks (possibly as a result of the changes above), simply increase the buffering in: Options > Playback > Output Mode Settings...

Also, try WaveOut instead of DirectSound.

Finally, turn off sample-rate conversion or other CPU-hungry DSPs.

When properly configured, MC is very skip resistant.  We were testing on a PIII 500 yesterday and could bring Winamp and WMP to its knees by hogging the CPU with a stress tester, but couldn't get MC to skip.
